This is an iMac right? Which means it is an all-in-one computer. Which means, like all iMacs, it is probably very difficult to repair. Some of the older iMacs had a port in the back for an external monitor. If yours does try that. I assume this has an LCD screen. If it does and if that has gone bad and if it could be replaced, it would probably cost more than the unit is worth.

First (and this is going to sound stupid) check that it has both power and is connected to the computer. Second, if it turns on check that it is recieving a signal. For video cards, most computers keep the default display adapter as the built in one and you have to manually change it in your CMOS settings. Third, make sure that your computer or screen isn't burnt out. This can happen and is noticible if your screen says nothing or your computer doesn't output a signal. If you aren't sure check your screen with someone elses computer.

My computer starts up and you hear the chime andthe little led lighton the bottom right lights up and stays solid but the screen remains black. i still hear sounds from the mac but i still have a black...


If the light stays solid for as long as you have it on then I would say that the logic board is dead. I would not bother fixing it, a new logic board costs almost as much as your computer on ebay used. If you still prefer to replace it yourself here is a link to the logic board and here is a guide to replace it.
However, if the light comes on and then goes off it is probably the screen.Guide Part.

IMac freezes on startup. Can't use safemode.


Safe mode just requires holding shift down during start up and if it starts up at all this should be possible. Once in safe mode, you should be able to use Disk Utility to Verify disk and Fix Permissions. To Repair disk or with/without safe mode you need to startup with your install disk and on the first screen or after selecting language, use options to select Disk Utility. You really should tell us the MacOS version--10.3.9 10.4.11 10.5.8 or 10.6 are current and tell us your install disk version, too. With safe mode you can use terminal to run fsck to fix the disk, read the man page. Alternatives include starting up in Target Disk Mode (command+t at startup) and using your computer as an external disk for another Mac by Firewire or possibly USB, fixing it using the others software. These methods in descending ease.
A now permanently dark screen would indicate a bigger problem and a trip to an Apple store for an evaluation. Tell us your iMac model--could affect whether you can easily savage your disk data in this case. -Ken

White bar on right side of screen


Try a reboot. If it remains, shut down and leave off for about an hour. If it comes back you probably have a problem with your video card. You can have it replaced (it will be pricey though), or consider getting a new computer. I had a similar issue with an Intel iMac 24-inch out of warranty and had the card replaced but your machine is much older.

Monitor won't "sync"


Analysis procedure on this one is straightforward, though equipment intensive.
1) Put a different display on the Mac and see if it works better.
2) Put a different computer on the display and see if it works better.
Until you do this, we don't even know what component is at fault. Once we do, you can proceed from there.

Power light goes out but power remains thru the m-board fan runs


you need to replace the power supply. The fan sound is the fan for the power supply and not the computer. for cheap parts or used goto headgap's. They know what you need and probably even help you replace it yourself.

Apple G5 Locked up


Sounds like you have a permissions issue, first boot in single-user mode and repair permissions.
Resolve startup issues and perform disk maintenance with Disk Utility and fsck

Mac OS X: How to start up in single-user or verbose mode

If that doesn't help, try booting into Safe Mode and see what happens, if it comes up hopefully another restart may solve, if not, you can at least use this as a starting point to try and resolve. Safe Mode will allow you to get around, surf, etc...

If Safe Mode comes up alright, I would install AppleJack, excellent troubleshooting article can be found here... Troubleshooting Tools: AppleJack
